Application led March 29,'1919.' Serial No. 286,025.`

To all whom t may concern.'

Be it known that I, ANTON JELINEK, a citizen of the United States of America, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Violin- Bows, of which the following is a specification.

This invention relates to certain new and useful improvements in violin bows or the like and has particular reference to an improved means for detachably fastening the ends of the horsehairs to the ends of bows of this kind whereby an inexperienced person may readily replace broken or wornout horsehairs from time to time at 'will as found necessary.

The primary object of the present invention is to so construct the fastening means as to most eiiiciently and quickly enable the replacement of these horsehairs.

A further objectof the invention is to provide fastening means of the present kind which shall be durable and eiiicient in operation and capable-of being cheaply and easily manufactured.

A still further object of the invention is to provide a fastening means of this kind involving a slight modification only of the bows which are now on the market coperating with adjuncts devised by me.

With the above general objects in view and others that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanyingdrawing and claimed.

In the accompanying drawing, forming part of this specification, wherein like reference characters indicate similar parts throughout the several views,

Fig. 10 is an enlarged perspective view of the attaching member or slipper for the outer end of the bow with the movable clamping plate thereof removed, and

Fig. 11 is an enlarged perspective view of the movable clamping plate of the fastening device for the outer end of the bow.

Referring more in detail to the several views, the present invention provides for the modification of the usual violin bow or the like which comprises the usual staff 5 having an enlarged laterally directed outer end 6 to which the horsehairs 7 are usually fastened in more or less crude and undesirable manners, the nature of which makes it impossible practically for an inexperienced person to fasten these horsehairs in place and to remove the same at will when found necessary for renewal thereof. In order that this fastening may be made quickly and easily by an inexperienced person, I provide the outer end 6 with a socket 8 extending inwardly from the end face thereof as clearly shown in Fig. 1. The end of the laterally projecting portion 6 is provided with a laterally extending toe 9 adapted for reception within the socket formed by the toe portion 10 of the slipper member l1 which is preferably formed of metal to provide a pair of substantially parallel converging flanges 12 adapted for interlocking connec tion with the end 6 as shown clearly in Fig.v

6 so as to retain said slipper 11 in position upon the end 6. The slipper member 11 has an aperture 13 in the sole or base member 14 thereof arranged to coincide with the socket 8 so that the horsehairs 7 may have their bound'l ends inserted into the socket 8 through the aperture 13 as shown in Fig. 1. The end of the laterally projecting p or tion 6 is also grooved as at 15 for reception of the inwardly extending lug 16 rigid with the end of the base member 14 opposite to the toe portion 10 of the slipper 11, said lug 16 being provided with a threaded aperture 17 whose axis is substantially parallel with the longitudinal axis of the staff 5 and which is adapted for threaded reception of the shank 18 of the adjusting bolt or screw 19. A clamping member 20, preferably formed by stamping from sheet metal is arranged within the slipper 11 upon the base portion 14 and between the flanges 12 there of, the base 21 of the clamping member being slidably-arranged upon the portion 14 between the lug 16 and the toe portion 10. A clamping jaw 22 is provided on the base portion 21 of the clamping member 2O so as to extend inwardly at right angles to said base portion 21, and a flange 23 is formed on the base portion 21 in parallel spaced relation to the jaw 22 and provided witlra cut-out edge 24 adapted for reception within an annular groove provided around the inner end of the screw 19 so as to provide a swivel connection between the clamping member 20 and said screw 19.

' 1t will be obvious that when the liorseliairs are inserted through the aperture 13 into 'the socket 8 as shown in Fig. 1, said horsehairs will be securely clamped between the jaw 22 of the clamping member and the opposing wall of the soci-:et 8 upon rotation of the screw 19 iii the proper direction whereby said clamping member is slid upon the base member 14 of' the slipper 11 away from the lug 16. 1n operation, this clamping of the horsehairs has been found to also produce a flattening or spreading of the same into a uniform ribbon-like arrangement such as is desirable and often found extremely hard to do by means of prior fastening devices. It is also noted that, in practice, the tightening of the clamping member 2O when the horsehairs 7 are taut, also exerts a pull upon the slipper 11 in a direction so as to cause the extension 9 of the end 6 to be forced tightly into the toe portion 10 of said slipper, thereby assisting the flanges 12 in securely and rigidly res taining the slipper in position upon the end of the laterally extending portion 6.

The inner end of the staff 5 is provided with the usual longitudinal bore 25 adapted for reception of the adjusting screw 26 which is operated by the handle 27 to adjust the frog 28, said adjustment being effected by the threaded engagement of the shank of the screw 26 with the bore of the head 29 which is formed on the screw 30 and which is arranged withinthe enlarged slot 31 inthe adjacent portion of the staff 5,

said screw extending laterally through said slot and being threaded into the frog 28 as shown. The construction of the adjusting means thus far described is substantially the saine as that of the devices which are at present on the market, the adjustment being designed so as to move the frog 28 longitudinallyof the sta' 5 away from the laterally projecting portion 6 so as to produce a tightening of the liorseliairs 7 after the latter have been fastened to the end 6 and the frog 28. 1n order to provide an improved and convenient means for detachably fastening the liorseliairs to the frog 28, 1 provide the screw 30 with a reduced threaded extension 32 which projects into the chamber 33 provided in the frog 28, said chamber being formed by cutting out the frog so as to provide a shoulder 34 and an inclined surface 35 for purposes which will presently become apparent.

A nut 36 provided with a ball-shaped end 37 is threaded upon the reduced extension 32, said ball-shaped end being retained within the similarly shaped socket 38 of the clamping member 39 by upsetting the latter as at 40 as clearly shown in Fig. 8, whereby said clamping member 39 has a` rocking movement relative to the extension 32 and the nut 36. The outer face of the frog 28 is provided with a dove-tail groove 41 for reception of the dove-tail'slide 42 so as to close the chamber 33, said slide being provided with a reduced end 43 in spaced relation to the projecting arm 44 of the frog 28, thus forming an entrance opening through which the horseliairs 7 may extend with the free end of the same upon the inclined face 35 within the chamber 33.

1t will be seen that, when the nut 36 is threaded upon the extension 32, the end 45 of the clamping member 39 will ultimately come in contact with the shoulder 34, thereby rocking said clamping member upon its mounting 37 and 38 and consequently causing the engaging end 46 of said clamping member to bind the liorseliairs against the face 35, thereby also causing a substantial spreading of' the liorseliairs or a flattening of the same.

"When the liorseliairs have been clamped in this manner, the slide 42 is positioned so as to close the chamber 33, whereupon a properly shaped ferrule 47 is slid onto the arm 44 of the frog 28 and upon the reduced extension 43 of the slide 42. A wedge 48 is then inserted in the passage formed by the space between the arm 44 and the eXtension 43 so as to cause a further flattening and spreading of the liorseliairs into a ribbon-like form as hereinbefore made mention of in connection with the clamping means at the outer end of the bow 5. rlfhe wedge 48 is preferably formed of a flat piece of sheet metal and provided with an angularly bent end 49 arranged to flatly engage the end face of the arm 44 and thereby provide a finished appearence to the device as clearly shown in Fig. 4, said end 49 serving to also retain thel ferrule 47 in position.

F rom the foregoing description, the fact that ready renewal 0f the horsehairs may be accomplished by an inexperienced person through the medium of the present invention will be readily appreciated by those skilled in the art, it being noted that the release of the horsehairs can be easily eEected by the mere turning of a nut and an adjusting screw respectively indicated at 36 and l2 in the drawings. If desired, the nut 86 and the head of the screw 19 may be so fashioned as to be readily operated by a key or wrench of the type universally employed in connection with the winding and regulating of clocks.

It is believed that the construction and operation as well as the many desirable advantages of the present invention will be readily understood from the foregoing description, and while the form of the invention herein shown and described is what is believed to be the preferable embodiment thereof, it is nevertheless to be understood that minor changes may be made in the form, combination and arrangement of parts without departing from the spirit and scope of the invention as claimed.
